Triple

Target class: radioisotope
Context triple: [californium-252, instanceOf, radioisotope]

• A. radioactive material chosen
  Radioactive material is any substance that contains unstable atomic nuclei which spontaneously emit ionizing radiation as they decay into more stable forms.
• B. radiochemist
  A radiochemist is a scientist who studies and applies the chemical properties and reactions of radioactive materials for uses such as medical imaging, cancer treatment, and nuclear research.
• C. radioisotope thermoelectric generator
  A radioisotope thermoelectric generator is a device that converts heat released by the radioactive decay of isotopes into electricity using thermocouples, typically for long-duration power in remote or space environments.
• D. unit of radioactivity
  A unit of radioactivity is a measure that quantifies the rate at which unstable atomic nuclei undergo radioactive decay, typically expressed in becquerels or curies.
• E. ionizing radiation
  Ionizing radiation is high-energy electromagnetic waves or particles that carry enough energy to remove tightly bound electrons from atoms or molecules, thereby ionizing them and potentially causing chemical and biological damage.
• F. None of above.
